Ken-Bambu's place is excellent. Soi 2 is the perfect street to stay on in the area. It is easily walkable to the nightlife on Soi 4 (Nana), but quieter at night for a nice respite. The Nana BTS train station is right there, as is a few great late night food options. For groceries, the Villa Market, towards the main road in the Phloen Chit Center, has everything. Highly recommend!
